In this five-part series, presenter Peter Hayden travels through some of New Zealand’s most awe-inspiring landscapes. The series was made to coincide with the centennial of the establishment of Tongariro, Aotearoa’s first national park (and the fourth worldwide). Hayden traverses the famous Tongariro Crossing with priest Max Mariu, volcanologist Jim Cole, park ranger Russell Montgomery, and the young Tumu Te Heu Heu. It was the first time Tumu, later paramount chief of Ngāti Tuwharetoa, had been up the maunga; the power of his experience is clear and moving.
